How to avoid duplicate legend labels in story mode or transfer custom legend labels
How to avoid duplicate titles in subheadings? One way I could do this in matplotlib is to pass custom legend labels to the legend object. I couldn't find any documentation for an equivalent option in the plot. Any ideas?
traces = []
colors = {'Iris-setosa': 'rgb(31, 119, 180)',
'Iris-versicolor': 'rgb(255, 127, 14)',
'Iris-virginica': 'rgb(44, 160, 44)'}
for col in range(4):
for key in colors:
traces.append(Histogram(x=X[y==key, col],
opacity=0.75,
xaxis='x%s' %(col+1),
marker=Marker(color=colors[key]),
name=key
)
)
data = Data(traces)
layout = Layout(barmode='overlay',
xaxis=XAxis(domain=[0, 0.25], title='sepal length (cm)'),
xaxis2=XAxis(domain=[0.3, 0.5], title='sepal width (cm)'),
xaxis3=XAxis(domain=[0.55, 0.75], title='petal length (cm)'),
xaxis4=XAxis(domain=[0.8, 1], title='petal width (cm)'),
yaxis=YAxis(title='count'),
title='Distribution of the different Iris flower features')
fig = Figure(data=data, layout=layout)
py.iplot(fig)

Strictly controls this at the trace level. Try to go through showlegend=False
inside trails Histogram
that you don't want to show in the legend.

Example: https://plot.ly/python/legend/#Hiding-Legend-Entries
Direct copy-paste from the link above.
import plotly.plotly as py
from plotly.graph_objs import *

py.sign_in('Python-Demo-Account', 'gwt101uhh0')
trace1 = Scatter(
x=[0, 1, 2],
y=[1, 2, 3],
name='First Trace',
showlegend=False
)
trace2 = Scatter(
x=[0, 1, 2, 3],
y=[8, 4, 2, 0],
name='Second Trace',
showlegend=True
)
data = Data([trace1, trace2])
plot_url = py.plot(data, filename='show-legend')
The usage you want to see is shown in the trace1
above.
